God’s graces are infinite but not unreasonable. He does not grant or take back anything unreasonably. When world’s people use his favors for conceit, corruption, destruction and injustice, the same favors become the cause of their misfortune. Their favors are taken back and replaced with calamity. Their industries and technology turn destructive, and their society generates discord and discomfort, and even the speed devices become the cause of their retardation, because they have misused the graces.
